Note: A
I
mark in the address column shows that there is a bit that does not exist in its register.
*
The initial values of PRPHF (SFR=18H) are as follows :
When
RES
pin is reset : VBFF (bit 6) is set to "1" and CKOUT1 and 0 are set to "0".
When reset by the WDT or BRK instruction or by operation code trap : VBFF (bit 6) keeps the
value just before reset and CKOUT 1 and 0 are set to "0". In any cases, the state of the
OE
pin
is read for OERD (bit 7).
